Because of a calibration update for one of the James Webb Space Telescope’s main cameras, research using the first few weeks of data from the observatory may be flawed

UV light plus aluminium chloride as a catalyst can break down polystyrene so that it can be turned into a chemical used in fragrances and medicines

There are expected to be 3.7 billion air conditioners in operation by 2050. Using propane as the refrigerant could prevent a significant amount of climate warming by the end of the century

The Airbus Zephyr S, a military reconnaissance aircraft, has more than doubled the record it set in 2018 for an uncrewed flight duration

People with chronic constipation who ate an AI-recommended diet for six weeks had an average 2.5-fold increase in weekly complete bowel movements

The after-effects of nuclear war would be catastrophic for agriculture. Simulations show billions of people could starve depending on the size of the conflict

Adults who had the left or right hemisphere of their brain removed as children to treat epileptic seizures had accuracy scores of over 80 per cent on word and face recognition tasks

Simulations of a quantum computer made of six rubidium atoms suggest it could run a simple brain-inspired algorithm that can learn to remember and make simple decisions

More than a million large-nose antelopes now roam the Kazakhstan steppe, a big rebound from the 130,000 animals left after a fatal bacterial disease killed half of the population

Simulations suggest that Earth could theoretically host two more moons the size of the one we've got now, or several smaller moons

Male and female macaques in a Balinese sanctuary commonly use stone tools to masturbate, possibly because they have more leisure time than wild primates

A pair of astronomers say that classified US government sensors detected an interstellar meteor hitting Earth in 2014. Now they want to mount a $1.6 million expedition to find fragments of it on the sea floor

Simulations show that a 1000-day mission to Mars would expose astronauts to radiation doses above 1 sievert, even with metal shielding

There has been a lack of clarity over the risks of covid-19 and vaccines against it during pregnancy throughout much of the pandemic, with research now overwhelmingly supporting that pregnant people get vaccinated

An extinct volcano’s underground reservoir in Mississippi has supplied CO2 to US beverage makers and food processing companies for decades. But natural contamination has exacerbated an ongoing CO2 shortage

A 2021 experiment achieved the landmark milestone of nuclear fusion ignition, which data analysis has now confirmed – but attempts to recreate it over the last year haven’t been able to reach ignition again

Unlike people, 43 species of monkeys and apes are known to have so-called vocal membranes, which may prevent them from having precise voice control

Moving like an insect may not be the most efficient way for tiny flying robots to hover – they get more lift by taking advantage of vortices of air that form under their wings

Twenty people who were legally blind or visually impaired received a transplant of a cornea made from pig collagen. All of them had improved sight, including three who now have 20/20 vision after being legally blind

Some large, meat-eating dinosaurs such as Tyrannosaurus rex had keyhole-shaped eye sockets, and reconstructions suggest this helped them bite with greater force
